Questions:

What is it?

A processor is the base chip in the computer that controls and executes programs instructions.

What does it do?

The processor fetches the information, or code of a program and executes the code and then fetches the next set of instructions to execute.

How does it work?

There are many parts of a processor with many different functions, first is the data registry. The data registry is a collection of high speed memeory bits. Data is transfered to and from the registers via the bus' linked to the RAM (random access memory). Next we have the arithmatic functions which actually runs the programs. All chips use the Fetch-Execute cycle, whereby, instructions and data are fetched from memory, and then executed. And thats how the processor works!

Where are they manufactured/made/developed?

The Processors are manufactured in India and soon to be manufactured in China. Moors law is an example of how it has developed or a theory of how quickly it is developed. Moors law is the observation made in 1965 by Gordon Moore, co-founder of Intel, that the number of transistors per square inch on integrated circuits had doubled every year since the integrated circuit was invented. Moore predicted that this trend would continue for the foreseeable future. In subsequent years, the pace slowed down a bit, but data density has doubled approximately every 18 months, and this is the current definition of Moore's Law, which Moore himself has blessed. Most experts, including Moore himself, expect Moore's Law to hold for at least another two decades.

What is the timeline of its development?

Intel introduced the first processor in 1972 and it has greatly developed sinse then. The timeline of the development of the processor is explained in moors law.

How is it controlled?

What are common solutions for the problems?

What are examples for the devices?
